Armoloy coatings offer impressive resistance to hydrogen sulfide (H₂S), chlorides, brines, and other corrosive fluids encountered in upstream and midstream operations. They mitigate pitting, crevice corrosion, and stress corrosion cracking — making them ideal for components exposed to sour service, offshore conditions, or high-pressure fluid transport.

Oil and Gas Coatings
Corrosion and wear protection for downhole and oilfield equipment
OILFIELD PROTECTION SINCE 1957
Engineered Coatings for Downhole and Surface Equipment
Downhole environments and upstream drilling operations expose components to constant mechanical stress, high-pressure fluids, corrosive chemistry, and abrasive debris. Saltwater, hydrogen sulfide, and particle-laden flow can quickly degrade untreated metal through corrosion, erosion, and adhesive wear.
Armoloy oil and gas coatings are engineered to slow these failure mechanisms by improving how the base metal performs at the surface — without significantly altering part dimensions or tolerances. The result is a hard, low-friction finish that helps resist pitting, chemical attack, and metal-on-metal damage.
We work with reliability engineers, maintenance teams, and drilling operators to apply proven treatments that hold up under high-pressure, high-temperature (HPHT) conditions: Armoloy® Thin Dense Chrome (TDC), XADC® Diamond Chrome Plating, and Bi-Protec®.
Applied to downhole tools, valves, or extraction pump components, Armoloy coatings stabilize performance under load and extend service intervals. The result is more predictable operation, better flow efficiency, and measurable protection against unplanned downtime across upstream and midstream operations.
Oil and Gas Coatings & Surface Treatments
Optimizing Oilfield Flow and Component Life
In oilfield equipment, surface performance directly affects flow efficiency, wear life, and long-term reliability. Armoloy coatings improve these conditions by applying a low-friction, micronodular finish directly to fluid-handling and mechanical contact interfaces. Applied at a controlled thickness of 0.0001″ to 0.0003″ (2.5 to 7.5 microns) per side, the coatings reduce friction and can improve flow performance in pumps, high-cycle valves, and downhole tools.
Beyond initial performance gains, Armoloy coatings also help extend the usable life of expensive components. They can be chemically stripped and reapplied without altering the dimensional integrity or metallurgical properties of the base metal, allowing parts to be replated and returned to service multiple times.
For worn components with minor material loss, the recoating process can help restore original operating specifications while re-establishing corrosion and wear protection. This reduces replacement frequency, shortens maintenance lead times, and supports more predictable equipment performance across demanding upstream and midstream environments.
Oil and Gas Coating Applications
Armoloy oil and gas coatings support a wide range of oilfield infrastructure and component-level applications, including:
Upstream Drilling & Downhole Tools
- Mud Motor Rotors: Protects rotor lobes against severe particle erosion and abrasive drilling muds.

Frequently Asked Questions
Armoloy coatings are ideal for downhole tools, valves, pump rods, actuator components, wear rings, and sealing surfaces that experience high loads, friction, and chemical exposure. Whether you’re operating in drilling, extraction, or refining environments, our coatings improve durability, reduce metal-on-metal contact, and extend part life under extreme pressure and temperature.
Armoloy coatings maintain physical stability and surface hardness in high-pressure, high-temperature (HPHT) downhole environments up to 1,200°F (648°C). Unlike traditional polymers or organic industrial paints, the coating will not degrade, soften, or lose its low-friction characteristics under extreme thermal loads.
No, provided the application process is strictly controlled. To eliminate the risk of hydrogen embrittlement in high-strength steels and severe-service components, Armoloy’s plating protocols incorporate an immediate, mandatory post-plating thermal bake-out cycle. This processing is executed in strict compliance with ASTM F519 parameters, driving out any absorbed hydrogen before it can compromise the mechanical properties or structural integrity of the substrate alloy.
Yes. Armoloy coatings are engineered for precise, ultra-thin deposition, typically applied within a strict range of 0.0001 to 0.0003 inches (2.5 to 7.5 microns) per side. Because the application is uniform and highly repeatable across complex geometries, it adheres to critical design tolerances without requiring secondary grinding or machining, preserving the exact dimensional fit of valves, pumps, and downhole tool interfaces.
